Wide Surface Acoustic Touch Screen 18.5 Inch Overlay Controller Board
18.5 Inch Wide Screen Saw Touch Screen Overlay controller board
SAW resistive touch panels and screens offered by CJtouch come in sizes ranging from 8 to 32 inches with diagonal CTB sizes also available. These touch screens can be used with a bare finger, gloved finger, or stylus, and come with shielded connectors and 4096 X 4096 resolution. They provide stable “drift-free” operation, meaning the touch response is always accurate.When compared to capacitive and resistive touch screens, surface acoustic wave technology is superior. It provides better image clarity, resolution, and higher transmission of light. Because the SAW resistive touch panel is all glass, there are no layers that can be worn down; therefore, this technology has the longest life, especially when compared to other touch screen technologies on the market. SAW resistive touch panels have a quick response time, and can recognize the location and amount of pressure applied.
